Re: RES: Massive SPAM Increase

[Paul Dean <paul () thecave ws>]

Hya All,

Anyone bother to think about using the wonderful rbl lists provided by 
lots of fast healthy servers around the world.

IE spamcop.net,
abuseat.org,
spamhaus.org (although this one has some court orders against it, see 
http://it.slashdot.org/it/06/10/10/140203.shtml)
ordb.org

plus many many more.

Most of these have howto's posted for different MTA's or at least links 
to sites to help.

Once I started using these lists, my spam dropped from like 1000 a day 
to 20 a day, just configuring Postfix and 5 rbl's.
